Application filed November 17, 1930. mm No. 488,111. r

This invention relates to that class of apparatus known asvehicle jacks by means of which any of the wheels may be raised from the ground surface.

Such operations as changing the tires, making temporary repairs and the like can only be accomplished by relieving the wheel from the weight of the car and raising it off the ground while working on it.

The ordinary types of lifting jacks are notoriously inconvenient and hard to .operate, requiring very considerable muscular effortand experience to handle in an effective manner.

It is therefore an object of the present invention to provide an efficient device whereby any of the wheels may be raised to a suitable height with substantially no efi'ort on 1 part of an operator, preliminaryto making desired changes.

A further feature is in the provision of a raising vided with wheels of difierent dimensions with equal facility.

Another aim is to produce a raising device of extreme simplicity, stren h, and lightness of weight, well adapted to carried as part of the equipment of the car.

These several advantageousobjects are ac- Fig. 4 is a s1de elevational view of a car bee and axle showing a modified means for attaching the jack. I

numeral-10 designates a chassis fram l l l I device adapted to engage cars procomplished by the novel design, construction p is a fragmentary side elevationalsectional Referring to the figures in det iltle. s1 e member supported by a semi-elliptical 11 carried by an axle having wheels, at 1 at its ends, these wheels being provided with the usual type of inflatable tires 13.

As seen in Figs. 1 and 2, the leaves of the spring 11 are clamped at a point adj acently the front of the axle by a yoke having an inner stra bar 14 and an outer, longer bar 15, at the ont, held firmly by clamp bolts 16.

Set rigidly in the extending portion of the 60 clampl bar 15' is a stud ,17 having a spacing s oulder 18, and fixed rigidly to one of the longer edges of the bar 15, at a point midway the bolts 16, is a bar 19 of rectangular cross section extending in parallel with 66 the stud 17, these elements being permanent- 'ly a plied to each spring.

e jack. proper s composed of a stem 20 leading to an elon ated and enlarged head 21 in which are a series of spaced 0 enings 7 22 each adapted to receive the stud 1 while the bar 19 makes contact with the surface of the head.

The opposite end of the stem 20 blends 1nto a fan shaped web 23, which may be provided with openings to reduce unnecessary weight, the web having a flange at its perlphery one part 24 being straig t, flat and at a rig t angle to the stem, while on the oposite end the flange is arcuately curved as at 25, and provided with sharp serration 26 adapted to engage and grip a surface.

The extremit of the curved flange is closer to the head 21 t wet the oint blending into the level portion 24 and o viously'will be so 8 placed on the ground surface as to raise the wheel and corner of the car as the vehicle 1s advanced to cause the stem 20 to assume a perpendicular position. v

In the modification, shown in Figs. 4, 5 and 6, the permanent jack attachments 14 to 19 inclusive are dis used with but the main jack structure is emp oyed.

Inthis case a curved hook 30 of considerable width, is 'rovided w1th an extending lug 31 in-which is set a rigid pin 32 engageable in any of the openings 19 of the head, while a shouldered portion 330i theconcave hook 330 engages the side of the head 21. I

In operation the hook is disposed to engage the underside of the axle or that portion of the transmission casing surrounding 1t, as

seen in Fig. 4, and the car propelled a short distance forwardly whereupon the same rais- 5 in efiect is produced.

ue to the series of openings 22, the pins 17 or 32 may be entered at different heights relative to the base flange 24, thereby ena ling the,

jack to be used even when different diameters of'wheels are encountered and also to raise the wheels to a reasonable height from the ground surface.

Obviously, upon moving the car rearwardly thejack is released, permitting removal and storage within the car if desired.

While certain preferred embodiments of this device havebeen shown and described, it will be understood that changes in the form,

- arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as defined in the ap ended claims.

aving thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a jack for wheeled vehicles having an axle between each pair of wheels, a base member havin an arcuately curved portion providedwit teeth to engage a surface, a web having a stem integral with said base, an elongated head on said stem having a row of spaced rforations, a hook having a pin engagea le selectivel in any of the head perforations, said hoo adapted to partially as encircle the lower side of said axle, and an abutmenton said hook to engage the side of said head and stem.

2. A wheel raising jack comprising av ground engagin base member, a stem extend- 0 mg upwardly t erefrom a'nd formed with a series of vertically spaced openings in the upper end portion thereof, a hook for engagement with a part of the vehicle, a longitudinally extendingllu formed on the inner end portion of the 00% at one side thereof, and

a laterally extending pin carried by the lu for selective engagement in the holes formed in said stem, the inner end of the hook adapted to engage the side of the stem to limit the 50 swinging movement of the hook in one direction.
